SPRAYING FORMULA FOR THE CONTROL OF PEACH LEAF CURL 
There are three main considerations in spraying: 
1st. An effective spraying machine. 
2nd. A mixture that will do the work. 
3rd. A knowledge of the proper time to spray. 
The principle underlying spraying is to cover the foliage or 
wood of the plants thoroughly with a medium in which the fungus 
will not grow. Both diseases and destructive insects work rapidly 
and a delay of a few days may make the remedy ineffective. 
The "best time to spray for Peach Leaf Curl is just when buds 
are beginning to swell early in the spring. This is the most im¬ 
portant time, so if there is much rain right after spraying and 
before the leaves appear, the spraying should be repeated, same 
strength. 
First Spray--BORDEAUX MIXTURE 
Copper Sulphate (blue vitriol)... 6 lbs. 
Fresh Lime. 6 lbs. ' 
Sheep Dip... 1 qt. 
Caustic Soda (common lye). 1 lb. 
Water to make. 50 gal. 
Use about half the water to dissolve the copper sulphate, do 
this suspending the crystals near the surface in a coarse bag, 
(better let it stand overnight, as it takes a long tine to dissolve 
Put lime in another vessel, adding small amounts of water from tine 
to time until the lime is thoroughly slaked, strain, then add water 
to make 23 gallons. Dissolve caustic soda in lj- gal. wster, but 
don't mix with rest of solution until ready to use. Pour into Spra 
tank holding 50. gal. the lime solution and the copper sulphate 
solution, then add sheep dip and caustic soda solution. This must 
be used immediately after mixing, as it is not sa%e to use the next 
day if previously mixed.
